How to: Publish a Shared Data Source to a SharePoint Library
To publish a shared data source to a report server that is running in SharePoint integrated mode, you must set the report project properties in Report Designer. In the project properties, all references to servers, reports, and shared data sources must be fully qualified URLs.
You must have Member or Owner permission on the SharePoint site. For more information, see Publishing Data Sources and Reports to a SharePoint Site.
To publish a shared data source to a SharePoint site
In Business Intelligence Development Studio, open your existing or new Report Server project.
On the Project menu, click Properties. The <project> Property Pages dialog box opens.
Choose the Configuration you use to publish to a SharePoint site.
If you want to publish the shared data sources in your project and overwrite previously published shared data sources, set OverwriteDataSources to True.
(Optional) For TargetDataSourceFolder, type a URL to a SharePoint library or library folder. For example, http://TestServer/TestSite/Documents/DataSources.
If you do not specify a value, the TargetReportFolder value is used.
For TargetReportFolder, type a URL to a library or library folder. For example, http://TestServer/TestSite/Documents/Reports.
For TargetServerURL, type a URL to a SharePoint top-level site or subsite. If you do not specify a site, the default top-level site is used. For example, http://servername, http://servername/site, or http://servername/site/subsite.
In Solution Explorer, right-click the shared data source you want to publish, and click Deploy. The data source is published to the location specified in TargetDataSourceFolder. Deployment errors appear in the Output window.
After you publish a shared data source to a SharePoint site, the file name extension is changed to .rsds. You can edit and manage a shared data source directly on the SharePoint site.
